I have the option of upgrading by simply plugging in a 486DX2/66 or an Overdrive processor into the motherboard to replace the CPU. Is there a significant performance advantage of going with the Overdrive processor as compared to the 486DX2/66? What are people's opinions on the price/performance ratios of these two alternatives? Would it be more cost effective to simply go with a full upgrade to a PCI motherboard with a Pentium processor?

Any >idea? Is this a bug? >Command I used : output \4\0\1\2\3\5\6\7 > output \4\8\9\10 >Result : only \4 were transmitted! Kermit uses C strings. The string terminated at the NUL character. If you wish to send a NUL to the remote, then use \N with version 5A(190). Earlier versions than this will not accept the sequence. output \4\N\1\2\3\5\6\7 ~~ Some remotes will ignore the framing error and see the NUL character if you send them a break. I DO NOT RECOMMEND THIS IN ALL CASES, however, it may work if you use the \B sequence to send a break. If you want 5A(190), the source to cku190 is on kermit.columbia.edu in the test directory. It will build if you simply issue 'make linux' or 'make linuxtcp' if you want to include 'telnet' mode of kermit. -- Al Longyear longyear@netcom.com ------------------------------ From: jacek@eng1.uconn.edu (Jacek A.

Date: 09 Sep 1994 17:18:56 GMT I have a situation in my office where we have 5 printers in our office connected to Novell Print queues and an lpd.nlm that processes print requests from my linux network. I need a way to filter printer data before it gets to the lpd on my server. My current setup is to use lpr and a remote printer definition in my printcap. Unfortunately, this doesn't allow the data to be filtered through the apsfilter I was using for two page printouts and Postscript conversions. Someone suggested setting up two printer definitions, one local and one remote and have the local one send its output ot the remote, prefiltered. I haven't been able to get this to work as of yet. Can someone give me an explicit example of how this is done or suggest some alternative method that would allow filtering? I like the output produced by apsfilter. Also, does anyone know where there is a version of apsfilter later than v2.3?
